I did not mean to publish this build yet!

I accidentally clicked 'publish' and do not know how I can set it to private again.
However, I would really appreciate if you could write down some suggestions or give feedback!
Remember though that I am not from an english speaking country at all.
Also I do not want to make my builds too complicated.
I just want to show you a good build and explain my choices.
